Multiply the edge lengths of a right rectangular prism with length 1/2, width 1 1/2, and height 3/4 to show that the product is the same as the volume you found by packing the prism with unit cubes with an edge length of 1/4 inch.
Cube method:
Number of cubes: 3/6
Volume of each cube: 1/4×1/4×1/4=1/64
Volume of the prism:
v=36×1/64
=36/64
=9/16 cubic units
